OSGILLA'TING WATER-METER.

SPECIFICATION forming part of Letters Patent No. 431,622, dated July 8, 1890.

Application filed January 20, 1890.

To all whom it may concern.-

Be it known that I, RIOHARD J. ROGERS, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Water-Meters, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to water-meters, and is an improvement upon the invention described in the Letters Patent No. 373,608, granted to me November 22, 1887; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the drawings, and to the claims hereinafter given, and in which my invention is clearly pointed out.

Figure l of the drawings is a vertical longitudinal sectional elevation, the cutting plane being on the crooked line 1 1 in Figs. 2 and Fig. 2 is a vertical transverse section through the outer casing and feed-pipe on line 2 2 in Fig. 1, and showing the moving parts in end elevation. Fig. 3 is a horizontal section on line 3 3 in Fig. 2. Fig. 4 is a horizontal section through the feed-pipe and a small part of one side of the inclosing-casing on line 4 4 in Fig. 2; and Fig. 5 is a partial vertical longitudinal section of the oscillating cylinder on line 5 5 in Fig. 2.

In the drawings, A is the measuring-cylinder, provided at the center of its length with the trunnions A and A the former fitting into a bearing in the central ring or belt B, while the latter is provided with a socket to -receive the inner end of the discharge-pipe C, which screws into a threaded bearing in the opposite side of said ring or 'belt 13, as shown in Figs. 2 and 3.

The ring B has screwed into each side thereof a hollow cylinder B, having its outer Serial No. 337,451. (No model.)

a valve-seat a, against which is fitted. the double-ported slide-valve 19, secured to the valve-rod 12, extending the whole length of the cylinder A, and having bearings in ears 0 c, projecting from the heads A A of said cylinder, as shown in Figs. 1 and 2.

The ring B has secured to its inner surface, directly opposite the pipe 13 and at'a distance therefrom equal to the thickness of the valve 1), the valve-seat (1, having formed in opposite ends thereof two chambers d and d separated by the partition (1 and with the two ports e and e for the admission of. water to one or the other of said chambers accord ing as the valve 1) is at one extreme or the other of its movement. The chambers 01 and d have screwed therein the pipes e and c respectively, the outer ends of which are closed by suitable caps, and are provided in Each of the heads A A of the cylinder A I has cast in one piece therewith the bent pipe at, and has formed in its inner surface the recess a to receive the lever a mounted on the horizontal shaft at, extending through one side of the inclosure of said recess, and carrying on its end outside of said head the lever a as shown in Figs. 1, 2, and 5.

Each of the heads A A has formed on its outer surface the lug or shoulder a, with which the shoulder f on the lever f engages to lock the cylinder at the end which is in its most elevated position. The levers f are mounted on studs or fulcrum-pins set in the pipes e and 6 near the outer end'as shown in Figs. 2 and 4: and have set therein or formed thereon near their upper end the laterally-projecting pins or lugs f with which the levers a engage to move the levers f about their fulcrum-pins and disengage the shoulder f of said levers from the lugs a on the cylinder-heads when the piston D comes in contact with one or the other of the levers a and moves it into the recess (L The upper ends of the levers f are moved'toward the heads of the cylinder and into engagement with the lugs to by means of a counter-- weight f (shown in Fig. 5,) and this movement of said lever f, acting through the pins or lugs f, the levers a and rocker-shaft a",

causes the levers a to be moved inward toward the center of the cylinder as soon as the pressure of the piston is removed therefrom, as shown in Fig. 5. The lower end of the lever a also engages with the arm g, secured on the end of the valve-rod b, when it is moved outward by the piston and moves said rod a sufficient distance to reverse the position of the valve 1) and change the direction of current of water entering the outer casing.

The arms g are extended beyond the valverod b, and have formed on their extremities the pads g, located above the pipes e and c and in such positions relative to the orifices e and e that when the valve-rod b is at the extreme of its movement toward the right of Fig. 1 the pad 9' at the opposite or left-hand end of said rod will be directly over the orifice e and when said rod is moved to the limit of its stroke toward the left of Fig. 2, the pad 9' at the right-hand end of said Fig. 2 will be over the orifice 6 E and E are the inlet-valve casings, andF and F the exhaust-valve casing, all arranged in a row and connected together and to the curved pipes a and the trunnion A of the cylinder A by the pipes h, h',j,j, 7c, and k, as shown in Fig. 1.

The inlet-valve casings E and E are open at top and bottom, and have fitted therein the valves Z and Z, respectively, the stems of which project below the lower ends of their casings, the valve-seats being at the upper end of-said casings, as shown.

The exhaust-valve casings F and F have double walls m and m, the former extending a short distance above the latter, and has its upper end closed by the screw-cap m as shown. The inner cylinder m is open at top and bottom, and has formed on its upper end a seat upon which the valve n or n rests, the

stems of said valves projecting below their casings, as shown in Fig. 1.

The inlet-valve casing E and the exhaustvalve casing F are connected at their lower ends by the tie-bar 0, and the inlet-valve casing E and the exhaust-valve casing F are in like manner connected by the tie-bar 0, said bars 0 and 0' each having formed thereon downwardly projecting ears, to which are pivoted the levers o and 0 respectively. The levers 0 and 0 extend inward from their pivoted connections to the bars 0 and o beneath the exhaust-valve n and n, respect-.

ively, and outward to some distance beyond the inlet-valvesl and Z, respectively, and have their outer ends fitted to bearings in blocks 1 and 1), formed upon or secured to the pipes at and 6 as shown in Fig. 1. Said pipes e and e 'also have formed thereon or secured thereto the blocks or lugs 10 and 13 respectively, with which the inner ends of the levers o and 0 come in contact when the end of the cylinder .to which said lever is connected is depressed, I

as shown in Fig. 1. The operation of my invention is as follows: The meter being properly connected in the;

line of service-pipe and the outer casing andthe cylinder A being filled with water, with the several parts in the positions shown in the drawings, if the faucet be opened to draw water, water from the main enters the outer casing through pipe B port'e, pipe 6 and orifice e, and water from the interior of said cas ing enters beneath the inlet-valve Z',through pipes h and a to the interior of the cylinder Aat its right-hand end and moves the piston D toward the left of Figs. 1 and 3, and the water in said cylinder at the left of said piston is forced through pipes a'and h at the left of Fig. 1 around the inlet-valve stern Z, through pipe j, over the top of the inner cylinder m of the exhaust valve casing F, through pipe 7.: and the discharge-pipe C, to and through the faucet. (Not shown.) The piston D, when it has nearly completed its stroke toward the left of Figs. 1 and 3, comes in contact with the lower end of the lever a (see Fig. 5,) and forces it into the recess a thereby moving the lower end of the lever a which, acting upon the arm g, moves the valverod 1), with the valve 7), toward the left of Fig.

1, and at the same time disengages the lever f from the lug a at the left end of Fig. 1,thus leaving the cylinder unlocked, so that the weight of the piston will cause the left-hand end of said cylinder to be depressed and the right-hand end to beelevated, in which position it is locked by the lever f at that end of cylinder. When the valve 7) and its rod Z) are moved toward the left, as just described, the port e is closed and the port e is opened, so that the water entering the outer casing passes from the pipe 13 through port 6', pipe c and orifice e and as the pad g at the right of Fig. 1 has been moved over the orifice e the current or jet of water escaping through said orifice impinges upon said pad and assists in tilting the cylinder, thus enabling me to use a lighter piston than otherwise would be practical.

It will be seen that with the parts in the position shown in the drawings the left-hand inlet-valve and the right-hand exhaust-valve are closed, while the other valves are open, said valves all being moved and held in their open or closed positions by the action of the levers 0 and 0 thereonas they are vibrated about'their bearings at their outer ends by the rising and falling of the two ends of thev cylinder A. I have shown no register, but it is obvious that a register may be applied thereto and worked from the oscillating movement of the cylinder.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In an oscillating water-meter, the combination of the measuring-cylinder A, provided with the trunnions A and A an inclosingcasing composed of the central ring or band B, provided with the inlet-pipe B and the two cylinders B,fscrewed into said ring and 'havingt-heir outer ends closed by heads formed in one piece therewith, and the cylinder-supporting discharge-pipe O, screwed into said ring and forming a bearing for the hollow trunnion A 2. The combination of the outer casin g B B, provided with the inlet-pipe E the branch pipes e and 6 having orifices e ande respectively, the valve-seat (I, provided with the two ports e'and e, the measuring-cylinder A, mounted in trunnion-bearings at the center of its length, the valve-rod I), extending the whole length of said cylinder and mounted in bearings, so as to be movable endwise therein, the valve 1), attached to the middle of said rod and constructed and arranged to operate in conjunction with the seat d and ports e and e to determine the flow of the inlet-water through the pipes e and c and a pad g, mounted upon each end of the rod 1), constructed and arranged to be alternately acted upon bythe jet of water escaping from the orifice e or 6 3. The combination of an oscillating measuring-cylinder provided on the exterior of each head with a projecting lug or shoulder, two latch-levers constructed and arranged to engage with saidlugs or shoulders alternately at the end of the cylinder that is the most elevated to lock said cylinder, a reciprocating piston within said cylinder, a pendent vibratory lever mounted in the inner face of each cylinder-head on arocker-shaft, another pendent lever mounted on each of said rocker-shafts and arranged to act upon the latchlevers to disengage them from the lugs on said heads when the piston comes in contact with and vibrates the levers within the cylinder, substantially as described.

4. The combination of the cylinder A, the piston D, the lugs or shoulders a a, the levers f, provided with shoulders f and the pins or lugs f the valve-rod I), mounted in bearmgs on said cylinder and carrying the valve b, the arms g and pads g, mounted on each end of the valve-rod b, the pendent levers a and a and the rocker-shaft a all constructed, ar-

ranged, and operating substantially as .de-v

operating levers supported in fixed bearings at their outer ends, and each extending inward beneath an inlet and an exhaust valve in positions to act upon the lower ends of the stems of said valves projecting through their casings, and pivoted at points central between said outlet and exhaust casings to bars connecting said casings, substantially as described.

In testimony whereof I have signed. my name to this specification, in the presence of two subscribing witnesses, on this 17 th day of January, A. D. 1890.
